[Purpose] The purpose of this study was to compare the strength and endurance between open and closed kinematic chain exercises after anterior cruciate ligament reconstruction. [Subjects] Sixty-two subjects actively participating in rehabilitation for anterior cruciate ligament reconstruction for the last 3 month were chosen. Twenty-six subjects were excluded and consequently, the data of 36 subjects were analyzed. The participants were randomly divided into 2 groups for open or closed kinematic chain exercise. [Methods] Open or closed kinematic chain exercises were performed under direct supervision of 3 physical therapists for 30 minutes per session, 3 times a week for 12 weeks. Before and after the intervention, isokinetic strength, endurance, and squat strength were tested. [Results] In the comparison of the before and after exercise results, all variables showed significant differences. Open kinematic chain exercises resulted in a significantly greater gain in isokinetic strength and endurance of the extensor muscles than the closed kinematic chain exercises. [Conclusion] Open kinematic chain exercise is helpful for the development of strength and endurance of the knee extensor mechanism after anterior cruciate ligament reconstruction, and can be used effectively in a rehabilitation program.

[Purpose] This study investigated the effects of resistance exercise using Thera-band on balance of elderly adults. [Methods] Subjects (age range, 60–70 years) were randomly assigned to an experimental (n=12) or control group (n=12). The experimental group performed stretching and resistance exercises, and the control group performed stretching exercises only. Before and after the 5-week intervention, the participants’ static and dynamic balance were evaluated using the Berg Balance Scale, the Timed Up & Go Test, and the Tetrax Portable Multiple System (Tetrax Ltd., Ramat Gan, Israel) after 5 weeks. [Results] After the intervention, the values of the Tetrax in the weight distribution index with eyes open and that with eyes closed and the stability test index with eyes open were significantly lower in the resistance exercise group than in the control group, and the pre-test values were was significantly higher than the post-test values. However, there were no significant differences between groups in the values of the Berg Balance Scale, the Timed Up & Go Test, and the Tetrax stability test index with the eyes closed. [Conclusion] The findings of this study indicate that resistance exercise using the Thera-band is possible to improve the static and dynamic balance of elderly adults.
